Pyrus calleryana Decaisne. (Malaceae . ) 43987. Scions 

 of pear from Jamaica Plain, Mass. Presented by the 

 Arnold Arboretum. This wild Chinese pear is not un- 

 common In western Hupeh at an altitude of from 1000 

 to 1500 m. f and is easily recognizable by its compar- 

 atively small, crenate leaves and small flowers. This 

 pear maintains a vigorous and healthy appearance under 

 the most trying conditions, and might prove to be a 

 very desirable blight-resistant stock. Also the woolly 

 aphis, which attacks other species of pears, has not 

 been known to touch this species. (Adapted from Com-
